Ward Yes, they are duplicates. I bought only 1 candybar that day ;-)
But I see it everywhere: an 'incasso' from my bank is listed 3 times, money I send to a joint account is listed 3 times, an iDeal verification transaction for 1 cent is listed 3 times, etc. They are literally all over the place.
Regarding the handelsonderneming: indeed I found another transaction that day for 1 cent, but to another bunq user. The wrong mapping is visible on other transactions: a company called NYX*VendingWork (yeah, the candybar) is mapped to V-NIX.nl (something with drones?).
Some other feedback: I saw a transaction called 'Sufferd' and this turned out to be something that I send to someone I know (who made a mistake lol, hence the description) but in general I would not opt to use the description of the transaction as main title in your app.
